Product Detail

Working Principle

Kemai HM series hammer mill is mainly composed of a shell, a rotor, a bearing iron and a grate. The shell is divided into two parts, which are welded by cutting steel plates, and the other parts are connected by bolts. The interior of the case is inlaid with high manganese steel liner, easy to replace after wear; An array of hammers with regular distribution is installed on the spindle, and a rotor is formed with a turntable and a hammer shaft. The main engine drives the main shaft through the motor and the triangle belt, so that the rotor rotates, the hammer head is extended to all sides by the centrifugal force generated by the rotation, and the large material enters the crushing chamber from the feed port, and is smashed by the high-speed hammer. The crushed qualified material is discharged by the grate with gaps at the bottom, and the unqualified material is left in the crushing chamber, and is repeatedly acted on by the hammer and the bearing iron block until it can be discharged qualified. In order to avoid clogging, the water content of the crushed material is generally not more than 5%.

Characteristic and feature of HM series hammer mill

Low energy consumption: Grinding system power consumption is 20 ~ 30% lower than the ball mill, and with the increase of raw material water, the energy-saving effect is more obvious.

Durable wearing parts: Made of special raw materials, the service life of the wearing parts can generally reach more than one year, and 2-5 years when processing calcium carbonate and calcite.

Limiting mechanism: Prevents direct contact between the roller sleeve and the mill liner to avoid destructive and violent vibration caused by friction and collision between metals, increasing safety.

Fully sealed system: The system operates under negative pressure, ensuring no dust leakage and maintaining a clean environment.

Frequently Asked Questions

What is the working principle of the HM series hammer mill?

The HM series hammer mill features a rotor driven by a motor and triangle belt. As the rotor rotates at high speed, the hammer heads extend outwards due to centrifugal force. Materials enter the crushing chamber and are smashed by the fast-moving hammers and bearing iron blocks. Qualified materials pass through the bottom grate, while unqualified materials are retained for further crushing.

What is the maximum recommended water content for processed materials?

To prevent clogging in the crushing chamber and ensure smooth discharge through the bottom grate, the moisture content of the materials should generally not exceed 5%.

How energy-efficient is the HM series hammer mill?

The HM series hammer mill is highly efficient, with power consumption that is 20% to 30% lower than that of traditional ball mills. The energy-saving benefits become even more pronounced when processing raw materials with higher moisture levels.

What is the average lifespan of the wearing parts?

Made from specialized raw materials, the wearing parts generally last over a year. When processing less abrasive materials such as calcium carbonate and calcite, the service life of these parts can reach between 2 and 5 years.

How does the machine prevent destructive vibration and metal friction?

The mill is equipped with a limiting mechanism that prevents direct contact between the roller sleeve and the mill liner. This design avoids violent vibration and safety hazards caused by friction and metal-on-metal collision.

Is the HM hammer mill environmentally friendly and dust-free?

Yes, the HM hammer mill utilizes a fully sealed system operating under negative pressure, which prevents dust from escaping and ensures a clean, environmentally friendly workspace.
